JEE Main Chemistry question

Benzene --CH₃Cl/Anhydrous AlCl₃--> A --HNO₃(conc.) + H₂SO₄(conc.)--> B --(i) KMnO₄/KOH (ii) dil. H₂SO₄--> C. In this reaction, C is

(A)p-Nitrobenzoic acidCorrect
(B)m-Nitrobenzoic acid
(C)o-Nitrobenzoic acid
(D)2,4-Dinitrobenzoic acid

Answer: (A)

Solution

Friedel–Crafts alkylation of benzene with CH₃Cl/AlCl₃ gives toluene (A). Nitration of toluene (an o/p-director, –CH₃ activating) predominantly gives p-nitrotoluene as the major
